Specification of Letters Patent.

Patented July 13, 1909.

Application filed August 24, 1906. Serial No. 381,898'.

To all whom it may concern:

. Be it known that I, Josnru S. DUNCAN, a citizen of the United States, residing at Chicago, in the county of Cool; and State of Illinois, have invented new and useful Improveniente in Printing-Machines, of which the following is a specification.

The primary object of this invention is to enable circular letters to be printed in close imitation of ty ewritten letters andaddressed an'l completed) in one general operation of a machine. I y

Typewritten letters are rinted by taking the imprint of ty throug an inked ribbon on the paper an this gives to the letter a certain appearance or effect, which may be referred to as a ribbon eii'ect, and which is not found in letters printed without the inter osition of a ribbon between the type and t e paper.

M y invention also'has for its object to provide a machine for producing circular etters, printed and separately addressed, with this ribbon eii'ect or ap earance.

The invention also has or its object to print circular letters and at the saine time `print separate addresses on the letters, the addresses being borne by separate and independent printlngl devices arranged if desired, in accordance, with a card index system, and which are moved one at a. time from a pile, printed and returned in their original position in the card index s stem.

In an extensive list of ad resses, such as a subscription list, there willV often be male, female and plural addresses scattered indiseriminately therethroughand another object ofv my invention is to provide for automatically printing on a circular letter the proper salutation for any one of these addresses as ma. he required. Y

y, written letters are almost invariably si in a different colored ink from the rest of the letter and to secure a close imitation of the complete typewritten letter my invention has for its object further to stamp an autographic signature directly upon a letter after 1t :has been printed and addressed tllfough a ribbon and 1n a different colored 1 A still further object of the invention is to provides. -machine` of simple construction for accomplishing the objects hereinbefore mentioned and which can be operated by hand; and the invention has so various su tion show the ,other side of the machine.

Referring tothe drawin 1 designates a frame of suitable construction which is provided with a plurality of rollers 2 supporting a carriag 3. This carriage has a racl r 4 meshing wit a gear 5 on the main or drive sha-ft 6 whereby the carriage is moved rearward for the y urposes hereafter described, being guided y the guides 3. VThe'carringe is provided with a bed 7 to receivea 'letter form S which is bolted or otherwise rigidly secured on ,the bed in any suitable bed 7 to receive and support the `address printingdevice 10 (Figs. 5, 6, 17).

At he rear end of the machine (Fig. 1) ist a magazine '1-1 to receive the address printfin devices 10 fig. 17). '1i-his ma zine 15 stantially. `li e those illust 1n my former patents No. 764,660 dated July 12, 1904 and No. 803,677 dated Nov. 7, 1905. and for this reason need not be described in detail. The magazine is hinged to the frame so that it can be swung backward into an incliiied position to receive a sup 1 y of adf vis in the stack. A

dress vrinting devices, and this inge consists oa pair of threaded studs 13 projecting rearwardly from the magazine and passing through a transverse shaft 14 'ournaled in bearings in the brackets 15 on t e frame. The magazine is secured in adjusted position on the frame by nuts 16 carried by the threaded studs 13 on opposite sides of the shaft 14. This construction ermits the magazine to be properly adjuste on the .inachine relative to t e trave of thecarriage and also permits the magazine to be removed from the machine without changing the adjustment. The magazine is normally held rigidly in upright position by spring 17 which is connected to a lug 18 on the arm 19 pivoted at 20 to the frame. This arm has a shoulder 21 whic hengages a roller 22 on the ma azine. The'arm 19 is rovided with a soc et 23 to receive -the ro er 22 when the' magazine is swung rearwardly, and hold the ma' azine rigidly 1nthis inclined position.

T e stack of address (printing devices in the magazine is supporte on the projections 24 which permit these devices to be moved forwardone at a time from the bottom of the stack without disturbing the other dear 25 is mounted on the main drive shaft 6 (Fig. 5) fand meshes with a lar gear 26 mounted on the stud shaft 27 (gli 1,4, 6). A gear 28 on the shaft 29 mes es with the gear 26 and this shaft 29 is rovided with an operating handle 30. A ever 31 is rigidly mounted at one ond on the rock shaft 32 and its other end is pivotally connected at 33 with a, link 34 which is, pivotally connected to the carriage by a pin 35 (Fig. 1 An arin- 36 is also rigidly mounted on t e rock shaft 32 in an an ar position with relation to the lever 31 an is intermittently connected to the gear 26 by a connecting rod 37 which is pivotally' connected to said gear by the wrist pin 3S (Fig. 22. The connection between the arm 36 and he connecting rod 37 is shown in detail in F' 16, the rod being provided with a longitu inal slot 39 near its endand the arm havin a in 40 which works in said slot. A pair o spring actuated dogs 41 are mounted on the connecting rod 37 at its outer end and project inwardly to swing down be hind the pin 40 when the latter is at the extreme forward end of the slot: `A pin 42 on the dogs limits their downward movement. y

A cam 43 is arranged on theside ofthe frame in the path o .an anti-friction roller ;44 on'the dogs to raise the dogs vout of engagement with the pin 40 on `the rearward movement of 'the arm 36; A clutch strap 45 is pivotally mounted at 46 on the main frame and is provided with a roller 47 which travels in a grooved cam 48 keyed or otherwise ri idly fastened to the large gear 26 (Fig. 3 This clutch strap operates a clutch 49 which is arranged on the shaft 6 to make locking engagement with th gear 25.

The carriage is moved rearward (to the right from the position shown in Fig; 1) by the gear 5 operating the rack 4 and t is gear is rotated by the main shaft 6 which in turn is actuated by the handle 30 throu h the gears 28, 26 and 25 and the clutch. T e cam 48 is constructed to operate the clutch strap and throw the clutch in and out of engagement with the gear 25 to enable the carriage to reciprocate. Y

In view of the `fact that the movement of the carriage must be performed with extreme accuracy 1n order to rovide for the proper ositionin of the' a dress rinting device ed beneat the stack of said) devices inthe magazine I prefer to throw out the clutch before the rearward movement of the carriage is completed and complete this movement by means of the devices attached to the rear end of the carriage and o erated by the gear 26. I have Yconstructed e machine so that the cam will throw out the clutch when the carria Vhas arrived ,within a half inch of the limit of its rearward movement and at this time the in 40 will be located at the forward end o the slot 39 in the connecting rod. The continued revolution of the gear 26 swings the arm 36 forward and rocks the shaft 32 to swin carriage to'thev imit'of its rearward movement. `At this time the bed 9 is registering properly beneath the stack of address printing devices in' the magazine and the wrist pin 38 is passi its center. Then thecarriage be s its orward movementwhich is accomplishedentirel by the device connecting the gear end o the carriage with the gear wheel and while the clutch is disen a ed rom tl' gear 25. In this way I provi e or absolute re 'stration of.the bed 9 beneath the stack o address printing devices at each operation of the machine and while I have found it to Jbe desirable to disengage the clutchwhen the carriage is -within a half inch of the limit of its rearward movement this is discretionary and may be changed if found desirable. f

To remove the bottom address printing device from the stack I provide the carria with a pair of s ringl ressed dogs 50, wliic yield to ass t e en s 10' of the address printin evices 10 on the rearward movement o the carriage and spring into posiltion behind the ends of said address rinting device when the carriage reaches t e limit of its ,rearward movement in position to push the bottom printing device from beneath the lever Bland move the carriage. (Fig. 3.) The bed 9 is made to fit the address printing device and the dogs not onl operate to push the device forward from t e stack but also hold the device in place on the bed against rearward movement during the printing operation. The address rinting device is discharged from its bed immediately after it has printed and is then discharged into a tray 53 which rests in an inclined position on a su port 54 )ivotally mounted at 55 on the main frame lFig. 1). The tray is held in elevated position by a lever 56 which is pivoted at 57 to the Support 54 and is arranged to engage a pin 58 on the main frame to hold the support and tray in tilted position as shown in Fig. 1. The bed 9 is carried by a swinging frame 59 which is pivotally connected at 60 to the carriage and swings downwardly to discharge the printing device in the manner just described after it is printed. The swinging movement of this frame is produced by a roller 61 mounted on the frame 59 and arranged to travel on a track on the main frame. This track inclines downwardly and rearwardly at 62 to a horizontal part 63 and then inclines upwardly and rearwardly at 64. While the printingdevice is printin the frame 59 is supported y rollers 65 trave ing on short tracks 66 on the main frame (Fig. 5) and after the printing device has printed the rollers pass od tracks 66 and the roller 61 be ins to travel on the track 62 and suport tlie forward or free end of the frame 59. ile-the roller 61 is traveling down the track 62 the frame 59 finally tilts to a tion to discharge the printing device on the bed 9. They rinting device is discharged from said bed) on to ides which are inclined at their rear en s 67 and have a horiaantal part 68 and an inclined discharge end 69 located above the front end of the tray supported in tilted position on the support 54 to receive the printing device.

At the upper end o the track 64 is a horizontal track 70 on which the roller 61 rests when the carriage is at the endof its rearward movement. A switch 71 is pivoted on the mai-n frame at 72 in alinement with the track 70 and forms therewith a con-` tinuous track, the end 71' of said sw'itch bei beveled to fit against the track 64. As t e roller 61 travels n the track 64 it will raise the switch 71 andJ then pass on to the track 79, the switch Vfalling by rlivity into normal position, as shown in ig. 1. On the forward movement of the carriage the roller 61 will pass from the track `70 on to the switch 71 and thence back to the position shown in Fig. 1. The switch is pros vided in front of its pivot with an angularly disposed end 73 which acts as a, ide or V.to make the roller 61 travel own the incline traek`62 on the 'rearward movement of the carriage. 4It will be observed after the printing operation, the

that the bed frame carrying the address printing device is caused to swing into tilted position immediately after the address has been rinted to discharge the riiiti device t erefrom and then this rame is returned to its normal horizontal position to receive the bottom printing device in the stack by the time the carriage has reached the limit of its rearward movement. The rinting devices slide from the bed of the rame 59 when it is in its inclined position on to the inclined guides 67 and down these 'des to the horizontal part 68 thereof. A

spending finger 74 is carried by the frame 59 and is arranged to engage t e printing device resting on the uides 68 when the carriage moves forwar and push-it on to the inclined discharge end 69 thereof where it will fall by gravity into the tray.

The address printing devices are preferably arranged m trays in accordance with a regular card index system and it is important not to destroy this arrangement but to return the rinting devices after printing to their original position in the tray. 1n the ordinary operation of the machine the printing devices containedin the tray are discharged into the magazine with# out changing their arrangement and with the rinting device which was at the front of t e tray uppermost in the magazine. The tray is then arranged in tilted position on the support to receive the printin device ollower 75 having first been moved to the front of the tray.. The printing device which was at the rear end of the tray willbe printed lirst and discharged into the tray at the front end thereof in front of the follower. It then becomes necessary to pack the printingl devices in the tray and gradually move t e follower rearward therein. To

accomplish this automatically IY provide a aeker Vwhich consists of a 4bell-crank lever 6 pivoted at 77 on tliemain frame and hav an arm 78 which projects downward into t `e tray and a forwardly` projecting arm 79. A s ring 80 fastened to the frame and the arm 78 normally holds said arm at the front of the tray. A lever 81 is pivotally mounted on the cari-ia at 82 and'is normally held in inclined position as shown in Fig. 1 by a spring 83. The lower end of this lever is arranged to slide over the end 79 of the arm; 79 of the packer on the rearward movement of the carriage and seat itself in a socket 79 in said arm of the packer on the forward movement of the carriage. When the lever seats itselfV as just described it. will swing the ecker andeaus `.the arm 78 to push the ad rees printing device rearward in upright position in the tra 'lhe letter form, preferablyv inclinati the date, remains unchanged while the adress iio iso

is changin at each printing operation. It therefore ecomes necessary to provide a salutation as required by each particular address. Thus one address will require the single male salutation Dear Sir, another the single female salutation Dear Madam i and another the pluralA salutation Gentle men. The relative position and arrangement of these three salutations may be chan ed as found desirable to suit particular lists of addresses. For the pur ose of this description it will be assumed t .at the salutation most often used is the Dear Sir salutation and this is arranged in position to print at all times except when the salutan tion device is adjusted to bring one of the other salutations into rinting osition' to correspond with the address to e printed. The salutation forms are supported end to end on the edge of the late 84 which is rigidly mounted on a roc shaft 85 su ported on the carriage. The edge of this p ate has three straight sections 86, B7 and 88 angularly disposed with relation to each other and form the bases of contiguous segments of a circle described from the center of shaft 85, the Dear Sir form 86 being mounted on `the central section 86, the Gentlemen form 87 on the section 87 and the F Dear Madam form 88 on the section 88. These salutation forms are preferably made of metal type or logotypes and are secured in any suita lemanner on the late. The late is normally held with the ear Sir orm in horizontal printing position. (Fig. 7? and it is held -in this position by two centra izing levers 89 and 90 pivotally mounted on lthe rock shaft 85. These levers are arranged on opposite sides of a fixed vpin 91 on the carria e and are provided at their rear ends wit arms 89 and 90which are connected at their outer ends by a` spring 92 (Fig. 8) A pin 93 on the salutation plate projects between the two levers 89 and 90, and it will be readily understood that the spri 92 holds the levers 89 and 90 in contact wi the xed pin 91 on the carriageand the pin 93 on the late to centralize the plate and hold theorm which is most used, the Dear Sir form as heretofore described, in horizontal printing, position. The salutation plate is swun to bring one of the` other salutations in printing position by a connecting rod 94 pivotal-ly connected at one end 95 to the plate 84 and at its other` end 96 to one end of a lever 97 pivoted at 98.011 the carriage and carryn at its other end a roller 99 (Fi 3). W en the salutation plate is centraliz that is to say when the middle salutation is in printing'position, the lever 97 holds the rol er 99 in the position shown in Figli betweenV two bent, arms 100, 101 which are pivotally mounted independent of each other l at 102 on a bracket 103 formingpart 'of ythe .Si `'inain frame. A spring 104 suita y arranged operates to hold these arms normally separated at their outer free ends which are bent inwardly at 100 and 101', said arms forming tracks for the roller 99. The roller 9.9 travels back and forth with the carriage in a path extending through between the outer ends of these shifting arms when the salutation plate is centralized and in order to swing the salutation late to carry one of the other salutations into printing position one of these arms is moved automatically so that in the forward movement of the carriage the roller 99 will travel on the track formed by the arm and swingthe lever 97 on its pivot thereb through t e medium of the connecting ro 94, swinging the salutation plate properly to bring the desired salutation into printing position. Thisv movement of the shifting arms 100, 101 is effected by a pair of tumblers co erating with the printing devices, one tumb er being provided to cooperate with all printing devices constructed in a certain manner to cause the salutation required by that particular address to be brought into printing position. The other tumbler is constructed tol coperate with the other set of rinting devices which require the third sa utation. These tumblers are constructed and operated alike but are only operated by the articular address printing device with wlliich they are intended to coperate.

The tumblers comprise the pins 105 and 106 carried on one end of the levers 105', 106 which are pivoted independently of each other at 107 on the carriage. yThe other ends 105,", 106" (Figs. 3, 7) of these leversv are normally pro]ected forward by a sprin 108 to engage the end 10 of the printing device 10. The printing devices requiring the Gentlemen salutation are constructed to operate the tumbler lever 106 and the address printing devices requiring the Dear Madam salutation are constructed to o erate the tumbler lever 105', but the one ever will not be operated by the printing device constructed to operate the other lever. The printing devices may be constructed in various ways to effect the o eration of the tumblers as heretofore mentioned but I have shown in the drawings a. simple construction in which the end of those printing devices re uirin the Gentlemen salutation are in ente at 109 and the end of those printing devices requiritr the Dear Madam salutation are inden at 110 .to receive the ends of the tumbler levers. (Figs. 18, 19.) It will be understood, of course, that these indentations ma be located in any other position in the en of the printing devices to accom lish the desired result. EachY of the tumb er levers is provided with a downward projection 111 carrying an anti-friction roller 112 (Fig. 7) which is arranged to travel for, say the last half of the rearward travel and the first half of the forward travel of the carriage, in contact with the track 113 on the main frame which swings the levers on their pivot 107 to carry the ends 105, 106H away from the end of the printing device. Thisl is necessary to throw the tumbler levers` out of the path of the bottom printing device in the stack on the rearward movement of the carriage. The letter and date form, address and salutation forms print through a ribbon 114 which is held taut upon the forms and is automatically fed a predetermined distance at each operation of the machine. The ribbon is fastened at one end to a spirng roller 115 revolubly supported on the main frame and at its other end is fastened to a ratchet roller 116 provided at one end with a ratchet wheel 117 which is opei'ated by a feed pawl 118 and locked by a locking pawl 119, both of these pawls being spring pressed (Fig. 1)` The ratchet roller 11G is revolubly mounted on the front end of the carriage and of course moves with the carriage and during the rearward movenient of the carriage the ribbon is automatically wound up on the spring roller 115. On the forward'movement of the carriage the ratchet is fed forward one or more teeth to shift or feed the ribboneorrespondingly and this will be explained more fully hereafter.

The paper 120 is supported in a pile on a feed board 121 held in a tilted position on the main frame above the carria e when the latter is at its forward position The paper is fed inward by hand to feed mechanism which carries it beneath a platen i'oller 122 mounted on a shaft 123 journaled in the tog le levers 124 and also in the ends of the inks 125 which are pivotally mounted on the shaft 29. The links 125 constitute a Swingin frame which carries the platen roller an the toggle levers 124 are pivoted at 126 to the short toggle levers 127 ivoted at 128 on the main frame. The tog es operate to swing the platen frame an carry the platen into and out of operative position. The toggle levers 124 carry rollers 129 on their lower ends which are `arranged to`be engaged by a stop -130 ady mounted on the carria e near its front end and alstop 131 adjustab ymounted on the .carriage at its rear end. hen the stop 130 strikes the roller 1.29, on the rearward movement of the carriage, the toggle will be thrown oil' center allowing the spring 132 (Fig. 6) which is attached at its'npper end to the main frame and at its lower end justab to the swingingplaten frame, to pull the` platen up out of operative position. l/Vhen the -sto 131 engages the roller 129 on the forwar movement of the carriage the togle levers are thrown on center again and tghe lplaten roller is thereby moved to opera- Fig. 1).,

tive osition. In the drawings the toggles are s own slightly off center to lock them and prevent accidental upward movement of the platen roller. The stops can be adjusted on the carriage to control the movement of the platen as may be desired.

The paper feed mechanism of the machine comprises a positive feed roller 133 operating on the n per face of the paper and a plurality of idiier feed rollers 134 operating on the underface of the paper, the latter be ing carried by a shaft 135 housed in the recessed front end 121' of the feed board. The feed roller 133 is mounted on the shaft 136 which is journaled in a swinging frame 137 pivotally mounted on the platen shaft 123. The platen shaft carries a ear 138 which meshes with the gear 28 on t e shaft 29 and another gear 139 on the platen shaft (Fig. 5) meshes with an idler gear 140 mounted on the frame 137. This idler gear also meshes with a gear 141 on the feed roller 133 (Fi 6). A lever 142 is rigidly .mountedV on t ie idle-r feed roller shaft 135 and its u per end is connected b a link 143 to t e swin ing frame 137. Tlie lower end 142 of this ever is arranged in the path of a bell crank lever loosely mounted on the shaft 117 carrying the ratchet roller 117. This bell crank lever has an upwardly and rearwardly extending arm 144 which engages the lower end of the lever 142 and the other arin 145 of said bell-crank lever carries the feed pawl 118 (Fig. 1). As the carriage nieves rearward the arm 144 strikes the lever 142 and swings it on its pivot until the toggle formed by said lever and the linkv 143 crosses its center and is held locked in this position by a stop 146 on the link which engages the lever. The frame 137 is thus swun upward andthe feed roller carried out o operative positionas the front end of the `carriage passes rinting position. After the toggle is mov to locked position the carriage continuing its travel rearward carries the arm 144 under the lever 142,whereby said lever arm is depressed and the arm 145 carries forward the pawl 118 to feed the ratchet forward one step. Thus the ribbon is fed endwise at each o ration of the machine. o On the forwar movement of the carriage a block 147 adjustably mounted on the frame engagps the lower end of lever 142 and swings it ack to its normal position thus permitting the `frame 137 to lower and carry the feed roller 133 into operative position (Figs. 1, 6).

A plurality of fingers 1 48 are fastened rigidly on shaft 35 and are thrown upward, when said shaft is rocked with the lever 142, in the path of the sheet of paper next to be fed to the machine for the purpose of preventing the aper from. passing to printing iosition unti the carriage has moved to its initial position at the front end of the frame.

As just described the block 147 strikes the lever 142 and swings itback to lower the feed roller into operative position and this feed roller lowers upon the sheet of pa er which has been held in position by the ngers, the latter being swung downward out of the path of the aper at the same time that the feed roller 1s lowered into operative position.. The block 147 can be adjusted in any suitable manner lengthwise of the carriage and it is preferably located to..operate the lever 142 for the purposes heretofore described to bring the feed roller into operative .position before the forms are carried forward to printing position which is immediately below the center line of the platen roller. The feeding mechanism is thus brought into operation to move the paper forward before the carriage reaches printing osition because the printing will ordinarily )e done on letter paper having a printed headin and it is necessary to feed the sheet until t e headin thereonhas passed printing position be ore the printing operation can take place.

In the embodiment of my invention illustrated in the drawings the carriage lowers the platen roller but the feed roller 1s thrown in operation while the platen roller is ,elevated and before the carriage has reached the limit of its forward' movement. These movements can be otherwise ltimed and will be varied according to the articular construction of the machine, ut, as before stated, the feed roller will preferably be thrown into operation before the platen is lowered to operative position and also before any part of the form reaches printing posi: tion. This arrangement may of course be used for other reasons than because the aper is provided witli a printed heading an may be dispensed with entirely if desired.

The paper is fed by the roller 133 and the platen from printing position on guides 149 tSlFi 1, 10,11 fastened to lugs 149 on t e Iisnks 125 an thence upon sprln guides 150 fastened 'at- 151 to the main fra e and projecting u ward alongside the supplemental feed ro A1ers 152. Narrow friction rollers 153 are carried by links 154 pivoted on the shaft 155 of roller 152 and these rollers 153 are held in frictional engagement with the platen rhller by spring 156 arranged on the shaft 128. The main feed roller 133 is driven b aring from the platen roller shaft an Yt e supplemental feed roller 152 is frictionally driven by the rollers 153 which travel in contact with the platen roller. The

ars`139 140 and 141 for driving the main ed roll'er 133 aretimed so that said roller and the supplemental feed roller will travel at the same peripheral speed as the platen roller, although it is not absolutel essential that the supplemental feed ro er should travel at the same speed as the other rollers for the paper will have assed out of operative engagement with t e platen roller before arriving at operating engagement with the supplemental feed roller. The spring guides 150 hold the aper against the roller 152 and the latter eeds the aper upward on to the discharge table 157 w ich is mounted rigidly on the shaft 128. The shaft 128 is provided at its-ends with eccentric bushin 158 revolubly mounted in the main frame (Fig. 5) to allow for the vertical adjustment of the shaft to thereby adjust the platen roller and feed mechanism relative to the carriage.

The sheet of aper stops moving after it passes upward tween the spring ides 150 and the roller 152 and is prevente from moving downward by said roller. In this position a signature may be rinted on the sheet in a different colored mk from that used in printing the body of the letter and address, 1f desired, to complete the imitation typewritten letter. If this is not desired the 'signature device may be dis ensed with entirely but as I have hereto ore explained I prefer to print the signature on the letter because the letter will then more closely resemble a typewritten letter. This si nature device com rises a frame 160 (Fi 12 which is adjusta ly secured by hoo ed thumb screws 161 to the edges of the discharge table, the said frame having guides 162 slidably arranged in grooves 163 in said table. A sleeve 164 is arranged on a shaft 165 journaled in bearings in the signature ,frame and this sleeve carries at its ends lever arms 166 which support a rock 'shaft 167 to which the signature stamp 168 is ad- Y justably attached screws 169. Screws 170 operate through shaft 167 and bear upon the signature stamp to coperate with the screws 169 in securing a perfect adjustment ofthe stamp. The shaft 165 carries the segment of a miter gear 171 which meshes with a smaller segment 172 on a square shaft 173 suportedon the si nature frame at 174 and u1 ed in the lug 1 5 on the main frame. A- ever 176 is arranged on the square shaft 173 and is provided with a hub 177 which rotates in a lug 175 on the main frame and is held in place by a collar 179 on the square shaft. This lever 176 carries a roller 179 which is arranged in the ath of the lug 180 on the ear wheel 26. he lever 176 1s moved by t e engagement therewith of the lug 180 and the shaft 173 is turned ninety degrees which movement is communicated to the shaft 165 to swin the stamp against the sheet of paper. T e stamp normally rests on an ink pad 181 supported on the signature frame and the\ stam is thrown in the arc of a circle to printing position when the shaft 165 is actuated by a piu 182 workin in an openin 183 in a swiveled block 84. By the time the stamp has and whereby the proper salutation for the 4ist printed the lug 180 will have passed the lever 176 and a spring 185 fastened to the main frame of the machine andto the lever will return the lever and the square shaft and the other parts to normal position, the stamp resting on the ink pad.

The ink pad is carried by a frame 186 which is automatically shifted so that the Y stamp will not always contact with the same part thereof at each operation of the machine. The ink pad frame is fastened b a screwV 187 eccentrically to the dou le shoulder pin 188 operating in the signature frame and .carryin on its lower. end a ratchet wheel- 189. i lever 1907is pivoted on a stud 191 on the signature frame and carries a feed pawl 192 which operates on the ratchet and is held in engagement therewith by a spring 193. The lever is provided with a lug 194 which is arranged to be engaged by a lug 195 on the square shaft 173 whereby said lever is swung each time said shaft is operated and thus the pad is shifted at each operation of the machine, (Fi s. 12, 13).

While the machine has a number of parts and there are a number of o erations it will, when fully understood, be ound to be coinparativeiy simple in lits construction and general operation. x

In describing the several groups of mechanism I ha ve explained the operation thereof and how they coperate with each other and it will not be necessar now to review the several operations in etail. It is sufficient to say that a sheet of aper is fed into the machine, an address, the ro er salutation for the 'said address, an t e letter are printed thereon with or without a date through 'a ribbon, and afterward a signature is printed on the letter directly in a different colored ink from that of the remainder of the letter. Of course I may print the si ature in the saine colored ink as the rest o 'the letter but I refer to print it in a dif-A ause it will then more ferent colored ink closely imitate a typewritten letter. The printing operation 1s repeated rapidly, the same letter being printed each time but with a diiferent address and the proper salutation for the addre, and the mechanism whereby 'the address printing devices are VInoved to painting position and afterward discharged aiddre is moved to printing position are automatic in action. d

It has been pointed out heretofore that the machine is especial-ly designed for use in connection with address printing devices arranged in accordance with a card 'index system, provision being made for maintaining the order and arrangement of 'the 'addresses whiie they are passi through the machine and returning them in their eriginai Sos- 'tion 'in the ltrays in which they are store "Ihe machine will operate very rapidly aild can be run by power as well as manu a n TilVhat I claim and desire to secure by Letters Patent is: Y
